摘要： An infiltration amount measuring unit is provided to measure the amount of carrier liquid infiltrated in recording paper. An output signal of the infiltration amount measuring unit is input to a control device to be used to calculate a voltage supplied to a heat source (heater) in a pre-fixing unit. A signal of a paper temperature measuring unit is input to the control device, which determines whether a target temperature is reached. The control device estimates the amount of carrier liquid in a toner layer based on the information from the infiltration amount measuring unit. Then, the pre-fixing unit is controlled such that the amount of carrier liquid in the toner layer falls within an appropriate range, based on the estimation result of the amount of carrier liquid.
